SPECIFICATION formngpart of Letters Patent No. 646,340, dated March 27,1960. Application nea May 15,1899. serai 110.716,802. N model.)

To @ZZ whom it may 'concern/.-

Be it known that I, .IO'HN V. ALLEN, of South Weymouth,in the county ofNorfolk and State of Massachusetts, have invented certain new and usefulImprovements in Machines for Applying Stiffening-Pins to Inner Soles, ofwhich the following is a specification.

This invention relates to the manufacture of inner soles of thecharacter described in Letters Patent of the United States N o. 621,198,granted to me March 14, 1899. The said patent shows an inner sole havinga se- Aries of stiifeningpins inserted in its margin parallel to theplane of the inner sole and extending across the channeled portionthereof, whereby said portion is stiffened.

The present invention has for its object to provide a machine forapplying the stiffening-pins to an inner sole of this character;

and it consists in the novel features of construction and arrangementwhich I shall now proceed to describe and claim.

Of the accompanying drawings, Figures 1 and 2 represent side elevationsof a machine constructed inaccordance with my invention looking atopposite sides of the machine. Fig. 3 represents a top plan viewthereof. Fig. 4 represents a front elevation. Fig. 5 represents a rearelevation. Figs. 6 and 7 represent sections on the line 6 6 ofFig. 3.Figs. 8 and 9 represent sections on the line 8 8 of Fig. 6. Fig. 10represents a detail view in elevation and section of the wire-feedingmechanism. Fig. 11 represents a detailperspective view of the awl anddriver and their holder.

The same reference characters indicate the same parts in all thefigures.

Referring to the drawings, a designates the base of the machine, and d adesignate standards located near thc rear edge of the base and havingbearings at their upper ends for the main shaft b, upon which aremounted a belt-pulley b', a hand-wheel b2, and the various cams foroperating the mechanism of the machine. The inner sole to bc operatedupon is supported and fed between a stationary abutment c4, adjustablyaffixed in the front edge of the base a by means of a set= screw c5engaging its stem, and a feed Wheel or roll c, having a vertical shaftor pintle c',

carried in a bearing at the end of an arm c2, which is pivoted on a studc6 to the base a. The feed-roll c is yieldingly actuated in thedirection of the abutment c4 bythe action of 55 a spring c, interposedbetween a xed lug d3 on the base a and a stiff spring-arm c7, which isattached to the arm or ylever c2 andextends in a slightly-divergentrelation to the heel or rear end of said lever. The spring 6o 09surrounds a guide-rod cl2, attached to the spring-arm c7. A pin cl3,projecting upwardly from the base a and adapted to engage the heel ofthe lever c2, limits the movement of the feed-roll c in the direction ofthe abutment c4, and a hand-lever 014, pivoted at C15 to the side edgeof the base a and engaging the heel of the lever c2, provides a meansfor moving the feed-roll c away from the abutment c4 to insert or removethe work. The 7o feed-roll c is provided on its periphery with a milledrib c3, by means of which it may obtain a firm supporting anddrivinghold on the inner sole, and said feed-roll isl rotated step bystep to feed the inner sole by mechanism, including a ratchet-wheel 035,secured to the upper end of its pintle, a spring-pressed pawl o16,engaging said ratchet-wheel and carried bya lever c, pivoted on the studc5, and a pin cls, engaged with the slotted rear end of the 8o lever c17andl carried by a block c1, which is secured by a set-screw 021 to areciprocating bar 022. The rear end of said bar is pivoted to one arm ofa bell-crank lever c2, which is fulcrumed at 027 to a standard a4 on thebase a, 85 and is provided on its other arm with a roll 024, engagingthe edge of a cam c25 on the shaft b. Said roll is held in contact withsaid cam vby means of a spring c2, attached to the lever c23 and to oneof the standards a. The 9o front end of the bar 022 is guided by beingpassed through an aperture in the heel of the lever c2. The revolutionof the cam c?5 rocks the bell-crank lever o23 on its fulcrum andreciproeates the bar C22, causing the lever 017 to be oscillated and thefeed-roll c to be rotated in a step-by-step manner.

The pins which are driven into the margin of the inner sole are cut offone at a time from the end of a wire strip h, which may roo unwindffroma reel w', Fig. 1, mounted on or near the machine, and which passesbetween wire-feeding rollers e e', mounted to rotate in a vertical planeon the back of the standard a2, attached to the 'base a. The two rollershave their peripheries slightly grooved to firmly engage the wire, andthe roller e, which is mounted on a fixed stud, is rotated step by stepto feed the wire. For this purpose said roll e is provided with aratchetwheel e6, engaged by a spring-pawl e7, pivoted to the upper endof an oscillatory arm es. 'The latter is attached to a rock-shaft el?,having at its rear end an arm @14. A roll 615 on said arm is held incontact by a spring @16 with a cam e on the shaft b. Vhen said camrevolves, it is obvious that the shaft e12 will be rocked and thefeed-roll c rotated. The roll e', which acts as a presser, is mounted onan arm e2, pivoted at e3 to the standard a2, and its pressure againstthe wire is regulated by means of a screw e4, mounted in a stationarylug e5 and engaging the lower end of the arm e2.

As the wire w is fed it passes through a hole in a horizontal flange a5at the base of the standard a2 and is cut od in short lengths to formthe stiffening-pins by means of a reciprocatin g slide d, having at itsfront end a hole d5, which registers with the hole in the flange a5 whenthe slide reaches its rearmost position, as represented in Fig. G, andwhich is brought into vertical alinement with the space between thefeed-roll c and the abutment c4 when said slide is in its foremostposition, as represented in Fig. 7. The slide d is reciprocated by meansof a cam di on the shaft h engaging a roll d2, carried by an arm d',offset from the slide d, said slide having a retractingspring d4, whichholds said roll in contact with said cam. 'The slide is guided bypassing through an aperture in the standard a2 and another aperture inthe standard et, mounted on the base a. It will be observed that therear edge of the hole in the slide d, through which the wire lw passes,and the front edge of the hole in the flange d5, through which said wirepasses, constitute shear edges, which cut oif the wire w when the slided starts to move forward from its rearmost position. The cutting edgesmay be formed on hardened-steel plates attached to the standard a2 andthe slide d, respectively, or said slide and standard may be hardened ontheir contacting faces to insure the preservation of the cutting edges.

f represents an awl mounted to reciprocate vertically into and out ofthe space between the feed-roll c and the abutment c1 to make holes inthe edge of the inner sole, into which the stiifening-pins cut from theend of the wire w may be driven, and g represents a driver for drivingsaid pins into the inner sole. The awl f and driver g are secured bysetscrews f g in a quadrant-shaped holder h', attached to the lower endof avertical reciprocating bar h. The latter is mounted in guides orbearings on the standard a2, and between its upper and lower bearingsthere are attached to it two short arms or collars h2, connected by avertical elongated wristpin 72,3. Said pin occupies a slot 'i2 in theend of a lever t, pivoted on a vertical stud t" at the top of thestandard a6 and having a roll 3 on its rear end engaged by a cam i4 onthe' shaft h. A spring Q15 holds said roll in en gagement with the cam.The revolution of the cam i4 oscillates the lever 'L' in a horizontalplane and turns the bar h in its bearings, so as to bring either the awlf or l[he driver g into operative position in alinement with the spacebetween the feed-roll c and the abutment c4. The bar t is reciproeatedto impart an operative stroke to either the awl or driver by means of alever j, pivoted at vj2 to the standard a6 and having a cam-roll ja atits rear end, held in engagement by a spring .7'5 with a cam (i4 on theshaft b. The said arm ,7' is pivotally connected at j with a block 71,,

fitted loosely into a recess formed in a collar h4, which is heldbetween the collars h2 h2 on the bar h and is guided in its verticalmovements by a stationary plate 71,5, whose edge occupies a verticalgroove in the said collar h4.

During the operative strokes of the awl f and driver g the pressure ofthe feed-roll c upon the inner sole is increased to more firmly supportsaid inner sole by reason of the engagement of a collar 028, secured bya setscrew c2" to the reciprocating bar 022, with the spring-arm e7 onthe lever c2, which carries the feed-roll when said bar makes itsforward stroke. lVhen the bar 022 is retracted, as represented in Fig.2, the collar C28 moves out of engagement with the spring-arm c", andthere is then only the tension of the spring e9 to hold the feed-roll cin contact with the work; but when said bar 022 is projected forwardly,as represented in Fig. 3, the collar c28 presses against the arm ci, andthereby forces the feed-roll e with an increased yielding pressureagainst the work. The hand-lever c may be utilized at any time duringthe operation of the machine to release or insert the work.

From the foregoing description the operation of the machine becomesapparent. The inner sole s to be operated upon is placed between thefeed-roll c and the abutment c, with its edge presented vertically tothe awl The operator starts the machine, and the awlf descends and makesa hole in the edge of the inner sole, parallel to the general plane ofthe latter, as represented in Fig. G. The awl is then retracted, and theslide d, starting forward, severs a short length of wire from the end ofthe strap yw and Icarries the severed portion forward into alinementwith the inner sole The holder 7L has meanwhile been oscillated from theposition shown in Figs. G and 8 to that shown in Figs. 7 and 9, so as tobring the driver g into operative position. The bar h now descends andthe driver g enters the hole d5 in the end of the slide CZ and drivesthe pin contained therein down into the hole formed by the awl IOO IIO

the combination of an awl f in the inner sole. The driver g and theslide d are then retracted in succession, and the inner sole is fedforward to bring a fresh portion of its edge into position to beoperated upon, and the aforesaid cycle of roperations is repeated. Whenthe driver g takes its operative stroke, the awl f passes down on oneside of the slided, as will be evident upon an inspection of Fig. 9. Ahole C31, Fig. 8, is made in the abutment c4 to receive the awl duringsaid downward stroke of the driver. During the operation of the machinethe inner sole is guided by the operator.

I do not confine myself to the exact details of construction andarrangement hereinbefore set forth, as the same may be variouslymodified Without departing from the spirit of my invention. Forinstance, it is obvious that path-cams may be substituted for -the camsandsprings shown in the drawings for operating the parts of the machine.
